Thermal management for gas lubricated, high-speed turbomachinery
Jürg Alexander Schiffmann, Luis Eric Olmedo Ocampo, Wei Liu
High-speed turbomachinery is commonly designed to achieve high power densities. Limited space for active cooling results in a challenging thermal management. A thermal modeling approach leveraging modern declarative programming capabilities is presented, y ...
2023Melting pseudosymmetry and thermal expansion in 3-benzoylpropionic acid
The thermal behavior of 3-benzoylpropionic acid (BPA) was investigated using single-crystal and synchrotron powder X-diffraction, as well as differential scanning calorimetry analysis. The study revealed the existence of two subtly distinct structures of B ...
ROYAL SOC CHEMISTRY2023New Reliability Assessment of MEMS Components under Accumulative Testing for Space Applications
This dissertation proposes a novel accumulative test method for MEMS-based, commercial off-the-shelves inertial measure units (IMUs) from the automotive field. The need for clarification and augmentation of the corpus of knowledge on MEMS reliability for s ...
EPFL2021Investigation of femtosecond laser-tuned thermomechanical properties of fused silica
The thermomechanical properties of materials are among the most important properties for
designing precision instruments, in particular for devices seeking high-dimensional stability,
invariant temperature-elastic properties or low thermoelastic losses. De ...
EPFL2020Long‑term strain measurements of traffic and temperature effects on an RC bridge deck slab strengthened with an R‑UHPFRC layer
Eugen Brühwiler, Bartlomiej Wojciech Sawicki
This paper presents the results of 28-month-long monitoring of a slab portion of the Chillon viaducts in Switzerland using strain gauges and thermocouples. This post-tensioned reinforced concrete structure was strengthened with a layer of reinforced ultrah ...
2020Degradation analysis in mixed (MAPbI(3) and MAPbBr(3)) perovskite solar cells under thermal stress
Mohammad Khaja Nazeeruddin, Sanghyun Paek, Zubair Ahmad
The current study provides an insight into the thermal stability of perovskite solar cells (PSCs) and the factors causing their degradation. To this end, a systematic stability study was carried out on n-i-p type perovskite solar cells involving mesoporous ...
